In girls, menarche is a late marker of puberty. Primary amenorrhea is defined as the absence of menarche in ≥ 15-year-old females with developed secondary sexual characteristics and normal growth or in ≥13-year-old females without signs of pubertal development. Furthermore, evaluation for primary amenorrhea should be considered in the absence of menarche 3 years after thelarche (start of breast development) or 5 years after thelarche, if that occurred before the age of 10 years. A variety of disorders in the hypothalamus– pituitary–ovarian axis can lead to primary amenorrhea with delayed, arrested or normal pubertal development. Etiologies can be categorized as hypothalamic or pituitary disorders causing hypogonadotropic hypogonadism, gonadal disorders causing hypergonadotropic hypogonadism, disorders of other endocrine glands, and congenital utero–vaginal anomalies. This article gives a comprehensive review of the etiologies, diagnostics and management of primary amenorrhea from the perspective of pediatric endocrinologists and gynecologists. The goals of treatment vary European Journal of Endocrinology depending on both the etiology and the patient; with timely etiological diagnostics fertility may be attained even in those situations where no curable treatment exists.

The incidence of POI increases with age in reproductive-aged women, and it is highest in women by the age of 40 years. Reproductive function and the ability to have children is a defining factor in quality of life for many women. There are several methods of fertility preservation available to women with POI. Procreative management and preventive strategies for women with or at risk for POI are reviewed. Keywords: premature ovarian insufficiency; in vitro fertilization; donor oocyte; fertility preservation 1. Introduction Premature ovarian insufficiency (POI) is the loss of normal hormonal and reproductive function of ovaries in women before age 40 as the result of premature depletion of oocytes. POI is characterized by elevated gonadotrophin levels, hypoestrogenism, and amenorrhea, occurring years before the average age of menopause. Previously referred to as ovarian failure or early menopause, POI is now understood to be a condition that encompasses a range of impaired ovarian function, with clinical implications overlapping but not synonymous to that of physiologic menopause.

Available evidence suggests that testosterone f breast cancer controls breast epithelial growth through a balanced interaction between its two f ER-positive active metabolites: cell proliferation is promoted by estradiol while it is inhibited by f ER-negative dihydrotestosterone. A chronic overproduction of testosterone (e.g. ovarian stromal f androgen/estrogen balance hyperplasia) results in an increased estrogen production and cell proliferation that f androgen excess are no longer counterbalanced by dihydrotestosterone. This shift in the androgen/ f testosterone estrogen balance partakes in the genesis of ER-positive tumors. The mammary gland f estradiol is a modified apocrine gland, a fact rarely considered in breast carcinogenesis. When f dihydrotestosterone stimulated by androgens, apocrine cells synthesize epidermal growth factor (EGF) that triggers the ErbB family receptors. These include the EGF receptor and the human epithelial growth factor 2, both well known for stimulating cellular proliferation. As a result, an excessive production of androgens is capable of directly stimulating growth in apocrine and apocrine-like tumors, a subset of ER-negative/AR-positive tumors.

This miracle is a characteristic that all living things have in common and sets them apart from nonliving things. But even though the reproductive system is essential to keeping a species alive, it is not essential to keeping an individual alive. In human reproduction, two kinds of sex cells or gametes are involved. Sperm, the male gamete, and an egg or ovum, the female gamete must meet in the female reproductive system to create a new individual. For reproduction to occur, both the female and male reproductive systems are essential. While both the female and male reproductive systems are involved with producing, nourishing and transporting either the egg or sperm, they are different in shape and structure. The male has reproductive organs, or genitals, that are both inside and outside the pelvis, while the female has reproductive organs entirely within the pelvis. The male reproductive system consists of the testes and a series of ducts and glands. Sperm are produced in the testes and are transported through the reproductive ducts. These ducts include the epididymis, ductus deferens, ejaculatory duct and urethra. The reproductive glands produce secretions that become part of semen, the fluid that is ejaculated from the urethra. These glands include the seminal vesicles, prostate gland, and bulbourethral glands.

This mullerian anomaly occurs in 1 in 80,000-100,000 births. It is classified as type IB in the American Fertility Society Classification of mullerian anomalies. Case report: We report a case presented to POF Hospital, Wah cantt with primary amenorrhea and cyclic lower abdominal pain. She was diagnosed to have cervical agenesis associated with completely absent vagina. Conservative surgical approach to these patients involve uterovaginal anastomosis and cervical reconstruction. Creation of neovagina is necessary in these cases. Due to high failure rate and potential for complications, total hysterectomy with vaginoplasty is the treatment of choice by many authors. Conclusion: A thorough investigation of the patients with primary amenorrhea is necessary and total hysterectomy with vaginoplasty is feasible and should be considered as a first-line treatment option in cases of cervical and vaginal agenesis.

The most common of the Müllerian anomalies affect the uterus and may adversely impact reproductive outcomes highlighting the importance of gaining understanding of the genetic mechanisms that govern normal and abnormal development of the female reproductive tract. Modern molecular genetics with study of knock out animal models as well as several genetic syndromes featuring abnormalities of the female reproductive tract have identified candidate genes significant to this developmental pathway. Further emphasizing the importance of understanding female reproductive tract development, recent evidence has demonstrated expression of embryologically significant genes in the endometrium of adult mice and humans. This recent work suggests that these genes not only play a role in the proper structural development of the female reproductive tract but also may persist in adults to regulate proper function of the endometrium of the uterus.

  • Estrogen Deficiency During Menopause and Its Management: a Current Update V
    Review Article Estrogen deficiency during menopause and its management: A current update V. T. Hemalatha1, A. Julius2, S. P. Kishore Kumar3, L. Vijayalakshmi4, Shankar Narayanan1 ABSTRACT Different phases of a woman’s life: Puberty, menses, pregnancy, and menopause have varied influence on her oral health. During the menopause, women go through biological and endocrine changes, particularly in their sex steroid hormone production, affecting their health. Sex hormones strongly influence body fat distribution and adipocyte differentiation. Estrogens and testosterone differentially affect adipocyte physiology, but the importance of estrogens in the development of metabolic diseases during menopause is disputed. Estrogens and estrogens receptor regulate various aspects of glucose and lipid metabolism. Disturbances of this metabolic signal lead to the development of metabolic syndrome and a higher cardiovascular risk in woman. The absence of estrogens is a clue factor in the onset of cardiovascular disease during the menopausal period, which is characterized by lipid profile variations and predominant abdominal fat accumulation. However, influence of the absence of these hormones and its relationship to higher obesity in women during menopause is not clear. This systematic review discusses of the role of estrogens and estrogen receptors in adipocyte differentiation and its various effects and brief discussion on its management.

It is accompanied by cognitive, psychological, emotional, and sociocultural changes. There is wide variation in the timing of pubertal onset, and this process is affected by genetic and environmental influences. Disrupted puberty (delayed or absent) leading to hypogonadism may be caused by congenital or acquired etiologies and can have significant impact on both physical and psychosocial well-being. While adolescence is a time of growing autonomy and independence, it is also a time of vulnerability and thus, the impact of hypogonadism can have lasting effects. This review highlights the various forms of hypogonadism in adolescence and the clinical challenges in differentiating normal variants of puberty from pathological states. In addition, hormonal treatment, concerns regarding fertility, emotional support, and effective transition to adult care are discussed.
